Generator Arm Trivia C1

[Tom H.]

Re: Generator Arm Trivia C1

I knew I had one somewhere - here's one on the '57 fuelie chassis at Kissimmee; shows the correct shape (appears to be slightly less bend than the ones in your photos), but, as usual, painted wrong.

I know nothing about C1's, but how can this bracket so often be incorrectly painted? Does the judging guide specify the finish of this part ? Were the generator brackets ever painted engine color on any engine ?

Re: Generator Arm Trivia C1

John, like I mention both pic's you show is the the arm I show un-painted which was used for 55 to early 58 ONLY ,the generator that IS on the left side.The red arm is 58 up. You agree?

Roy -

I don't have any of the '58-'62 Assembly Manuals, but page 247 of Noland's book shows that #3770360 generator brace was used on '58 and '59 through December of '59, replaced by #3779210, which continued through the end of '62. 57's used #3704884. Don't know what 55's used.

Well I don't know how to answer Noland's but this is what I see all the time, but as I said take what I post as a grain of salt , anyone have a pic. Of Noland's article on the arm on a Corvette. Because I know 55 I'll stand behind that arm.#364 for a 55.

The current '56-'57 JG (4th Edition, currently under revision) was published in Summer 2000, and it says the brace was painted engine orange; don't know where that came from at the time, but it's incorrect.

Chevrolet Engineering documentation was published in "Vette Vues" magazine in 2001 (thanks to Ken Kayser) showing that installation of the brace was re-allocated from Flint V-8 to St. Louis in mid-1955 to resolve a chronic shipping damage issue; when that change was made, the brace was dip-primed black at St. Louis, and that practice continued through 1962. I believe the '56-'57 JG Revision Team understands this, so the brace will show as semi-gloss black when the new 5th Edition is published.

The Assembly Manual for '61 indicates #3779210 for the generator brace (sec 6, sheet 5, page A100).

Roy,

Since the generator is out of the car, it was easier to post a photo. I couldn't find a part number on it. I also don't know a great deal of history about the brace that was installed.

Let me know what you think.

That's the one I show it's correct , you cant go by the part numbers and some times GM prints , they change !
Some arms have the part number in them and some dont. That was the reason I posted this item under Trivia. I have prints showing some parts , but the real original part looks different. It has happened but again I might be wrong / ant the first time

I have one untouched since 1957 on the engine and it is still orange.

I think there is more to this story.

Re: Generator Arm Trivia C1

Roy I'm sure I have seen production line photos of completed engines on chassis's and they are all black. I think you may have posted them.

I for get what I post, others have posted engines also . I know the 55 was engine color, I think 56 to 57 was also (mine were) but people are confused (what year when ) and so on!
The color arguments are up to others not me!

Thanks!

Steve..from memory the engine is an oct 56 casting nov 56 assembly. I will look next chance I get. The generator arm is painted engine orange and has the part # stamped facing the fire wall. The engine still has its original paint as well. I don't doubt John's info but there may be reasons for engine painted arms...that should be considered for Judging.
